I have a Rotel-1067 reciever (7.1 surround and HD) and was wondering how to go about hooking up my Radeon 9800 XT video card and onboard audio to it. I have monster cables, 1/8 inch to red/white audio convertor, and a s-video cable. I also need to understand how to configure my computer to be able to display on this screen. Any help would be greatly appreciated.
